In response to a spate of insider revelations of corporate wrongdoing in recent years, the Cabinet endorsed a bill Tuesday to protect whistle-blowers from employer retaliation under certain conditions.

The government is aiming for Diet passage of the bill before the current session ends June 16, enabling it to take effect as early as April 2006, government officials said.

The bill would prevent employers from penalizing employees through dismissal, demotion or salary cuts for only revealing illegal corporate behavior that runs counter to the public interest.
